1998 jeep wrangler starting issues

jeeps are known for being hard to crank when cold so this is very normal!

When you're trying to start it for the first time of the day, look at the dash to see if the check engine light is on when you first turn on the ignition. If the check engine light is not lit up, your Jeep ecu is in need of repair and the vehicle will not start until that check engine light finally comes on.

Try disconnecting the upstream O2 sensor(s). If the sputtering stops replace the O2 sensor(s). Mine was faulty and stuttering too and no check engine light or code was thrown. After unplugging the O2 sensor and monitoring for a week with no issue I had it replaced for $100 - $150 at a local shop.

BAD PLUGS AND CLOGGED FUEL INJECTORS.

CHECK BATTERY VOLTAGE.IT SHOULD BE 12.5 VOLTS.IF BATTERY OKAY.YOUR FUEL FILTER COULD BE STOPPED UP.OR YOU NEED NEW PLUGS + WIRES + CAP AND ROTOR.

see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

bad battery or bad,corroded terminals

your fuel pump is bleeding off have it checked!

what this means is that either you have a low charge or your expansion valve is failing to operate properly. the expansion valve regulates the ther system which in turn allows the clutch to kick in . 4-5 years is generally the time a system needs a recharge anyway because the refrigerant starts to break down and the system no longer meets the minumum pressures. plus your dryer element most likely needs replacing as well thats where you get the smell from the crystal pellets inside the dryer are no longer any good

I know that a lot of starters will not start quickly and draw a lot of power if the engine is up to temp. Try a higher CCA battery (Cold Cranking Amp) Battery, your bat may be to low of a rating. If it has a remotely mounted solenoid, not on the starter. If it does it may be mounted somewhere that it gets to hot, relocate to a cooler portion of the engine bay.
